[Gloria] sent in Gottard. (English translation). This little box is designed to act as a stool – that happens to follow people around, record their conversations and play them back to other visitors as a form of interaction. A set of rotating casters provide seating support, while a pair of gutted cordless drills move things around. An Aurdino handles the robotic functions., and an iBook handles recording and playback. Ultrasonic sensors guide the movement, and a set of LEDs roughly show how full the recording drive is.
R/C quad-copters have been quite popular at CCCamp. Our friend, Dan Kaminsky shot this video of two different models in flight. The first is a 10K Euro commercial version, but the second one is a 500 Euro home built one. The commercial unit has a head mounted display so you can fly it from the onboard camera. There is a second video after the break that shows the maneuverability.
